PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 267,171, dated November'7, 1882.

Application filed May 4, 1882. (No model.)

To all whom it may concern:

Be it known that I, HENRY P. FEISTER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inPrinting-Machines, of which the following is a specification, referencebeing bad to the accompanyingdrawings, which form part thereof.

My invention has reference to printing-machines adapted to print uponboth sides of sheets and bind them into books, as shown in patentgranted to me April 18, 1882, No. 256,662, but more particularly to thenippers by which the sheets are reversed; and it consists in mechanismby which said nippers are actuated to receive the sheet, and after ithas been printed upon one side thereof reverse the same, and after ithas been printed upon the other side to separate said nippers todischarge the sheet; and,further,in combiningsaid mechanism with anendless chain of type-carriages and auxiliary mechanism, and in detailsof construction, all of which are fully set forth hereinafter.

In the drawings, Figure 1 is a sectional elevation, representing a chainof type-carriages and auxiliary mechanism, and having my im-. Fig. 2 isa sectional view or elevation of a portion of the chain oftype-carriages. Fig. 3 is a sectional elevation of my improved nipperson line 3 3/ of Fig. 4. Fig. 4 is a plan View, partly in section, ofsame; and Fig. 5 is a cross-section of the nipper-axle on line a: a: ofFig. 4. Fig. 6 is a transverse section taken on a line in front of thegripper-carryin g rods.

A is the chain of type-carriages, and consists of alternate carriages HH, hinged together to form an endless chain by shafts B, upon the endsof which are the supporting-wheels B, which run upon endless tracks I).The carriages H H are provided with lugs hh, through which the shafts Bpass to make a perfect hinge and prevent all lateral movement to saidcarriages independently of each other. Every alternate carriage, as H,is provided with nippers E E, and to allow room for the operatingmechanism they are separated at the top, as shown in Sheet 2.

To the end of each carriage H are bolted or theybeing all on the samecenter.

I I otherwise secured bearings K K K, those K K being for pins 7c 70 onthe ends of plates 0 O, and K being for the huh I of the pinion J., Arod, F, is secured to the plates 0 0 and pinion J and its huh I, and isarranged out of center, as shown. By this ineans,if the pinion isrotated, both of the plates 0 O are also rotated, Loosely journaled inthese plates 0 O and pinion J, and on each side of the center, are rodsL L, which carry, firmly secured thereon, the sets of clamping-straps M,three in number, and arranged equidistant from each other. The rods L Lare notched, as at Z l, and the nippers E E are arranged to be clampedand held 6 by said straps, and their ends fit into said notches, toprevent any possibility of their rotation on shafts L L. Said notchesperform the function of keys. Screws on lock the nippers to the strapsand secure them on the shafts or rods. A rod, N, and spring N keep thenippers pressed together, so as to clamp and hold the sheet of paper, Pbut it is evident that the springs might be arranged upon the rods or inother equivalent ways, and yet perform 7 5 the same function.

T represents the type, secured upon the carriages in any desired manner,and the nippers are made to meet on a plane coinciding with the face ofthe type. Toinsure this each of the rods L L is provided on its endswith levers Z, which are secured fast upon them, and, through the aid ofstops U U, cause the nippers to meet even with the face of the type.

The U-shaped piece Bis provided on one of 8 its legs with a rack, r, andupon the other with a guide-groove, r,in which the pinion respectivelymeshes and rotates. This piece R is guided in grooves r in thecarriagesH H, and by slot R upon flattened surfaces 11 of the shaft B,and by the pinion J and its hub, and,

if desired,the legs may be connected bya piece,

R Upon the bottom of piece R is the friction-roller S, which runs incam-groove S S S S, and by which the pinion is indirectly ro- 5 tated atproper intervals to reverse the sheet P from the type on carriage H tothat upon carriage H, or vice versa. The part S of the cam-groove causesthe nippers to hold the paper over the type on carriage H; part S causes1 oo them to reverse the paper and lay it over type on the carriage H;part B holds the nippers in the latter position, and part 8 causes themto gradually reverse back to the original position; but in so doing thecam V strikes one of the levers Z and opens the nippers to receive afresh sheet from the fingers W, upon which it is fed.

The type are inked by inking roller or cylinder D,provided withinking-facesdand notches d to span the nipper mechanism.

After the nippers have received asheet of paper it is laidover type oncarriage H, and after passing under the impression-cylinder G, andbefore it reaches the second impressionc linder, G, it is reversed bythe cam S onto the type on carriage H, and then passes under cylinder G,and is then printed upon both sides, and as it passes on one of thelevers Z is depressed by the cam V separating the nippers, and the sheetis run off by the tapes Y to the folding and binding mechanism.

The feed, the cylinders G G,having impression-surfacesg and spaces g,and the receiving, folding, and binding mechanism are substantially asshown in the patent granted to me and previously referred to.

It is evident that the nippers may be made to turn from carriages H tocarriages H while passing between the cylinders G G, which cylinders areadapted to print from every alternate carriage, the former printing fromcarriages H and the latter from carriages H.

When the machine is adapted to print pamphlets there are two beds oftype, T T, upon each carriage and three pair of nippers, as shown inFig. 4; but it is evident that there may be any number of nippers whenthe type is otherwise arranged, and, if desired, for some kinds ofprinting every carriage may be provided with a set of nippers.

I do not limit myself to the exact construction shown, as it may bemodified in various ways.

Having now described my invention, whatI claim as new, and desire tosecure by Letters Patent, is- V p 7 1. The combination of type-carriagesH H, hinged together at B, bearings K K K, plates 0 O, pinion J, withhuh I, rack-piece R, rigid rod F, loose rods L L. and nippers E E,substantially as set forth.

2. The combination of type-carriages H H, hinged together at B, bearingsK K, plates 0 0, pinion J, rack-piece It, rigid rod F, loose rods L L,levers Z Z, pins U U, nippers E E, and a spring to press them together,substantially as and for the purpose specified.

3. The combination of nipper-rods L L, notched at'l Z, clamps M, nippersE E, plates 0 O, the rod N, and spring N, substantially as and for thepurpose specified.

In testimony of which invention I hereunto set my hand.
